This script imports Ogre-Mesh models into Blender.
Supported:<br>
* multiple submeshes (triangle list)
* uvs
* materials (textures only)
* vertex colours
Missing:<br>
* submeshes provided as triangle strips and triangle fans
* materials (diffuse, ambient, specular, alpha mode, etc.)
* skeletons
* animations
Known issues:<br>
* blender only supports a single uv set, always the first is taken
and only the first texture unit in a material, even if it is not for
the first uv set.
* code is a bit hacky in parts.

# IN THE SOFTWARE.
# HISTORY:
# 0.1 04/02/05
# ------------
# * initial implementation. single submesh as triangle list, no uvs
#
# 0.2 04/03/05
# ------------
# * uv support added
# * texture loading added
#
# 0.3 04/09/05
# ------------
# * multiple submeshes added
# * scaling added
# * material parsing (only textures yet)
# * mesh -> mesh.xml conversion if IMPORT_OGREXMLCONVERTER defined
# * vertex colours
#
# 0.3.1 04/11/05
# --------------
# * stdout output streamlined
# * missing materials and textures are now handled gracefully
#
# 0.3.1a 04/11/05
# --------------
# * Mesh is assigned to a correctly named object and added
# to the current scene
#
# 0.4. 05/11/05
# --------------
# * shared vertices support
# * multiple texture coordinates in meshes are handled correctly no,
# but only the first coordinate set is used, since Blender doesn't
# allow multiple uvs.
# * only the first texture_unit's texture is used now.
#
# 0.4.1 06/02/05
# --------------
# * fixed bug: pathes invalid under linux
# * fixed bug: shared vertices were duplicated with each submesh
#
# 0.5.0 06/06/05
# --------------
# * consistent logging scheme with adjustable log level
# * render materials
#
# 0.5.1 13/07/05
# --------------
# * fixed bug: meshes without normals and texture coords cannot be imported
#
# 0.5.2 12/02/06
# --------------
# * fixed bug: multiple blender materials created from one ogre material
#
# TODO: implement a consistent naming scheme:
# bxxx for blender classes; oxxx for ogre(well, sorta) classes
